Application filed December 14, 18 2 6. Serial No. 154,687.

The invention relatesto a new and improved ventilator which is intended primarily for use in an opening formed in the windshield of an enclosedautomobile body, and in the present showing the ventilator embodies means for closing the opening to any required extent, as well as means for screening such opening to prevent the entrance of insects. j

It is one object of the invention to provide a novel construction and relation of shutters for closing the opening to the required extent.

A further aim is to make novel provision for securing the ventilator to a windshield or other analogous closure.

A still further aim is to provide novel means for securing the screen.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Fig. 1 is an inner side elevation of the ventilator withthe shutters partly open.

Fig. 2 is a vertical sectional view on line 22 of Fig. 1.

Fig. 3 is a view similar to Fig. 1 but showing the shutters closed.

Fig. 4 is a vertical sectional view on line 44 of Fig. 3. I

The form of construction selected for illustration in the present application will be rather specifically described, with the understanding however that within the scope of the invention as claimed, variations may be made.

The numeral 5 designates an annular frame member for passage throughan opening 6 in a windshield or the like 7, the inner edge of said frame member having an outwardly projecting flange 8 for disposition at one side of the windshield or other closure, a gasket 9 being preferably interposed between the two. A second frame member 10 of annular form is threaded upon the frame member 5 to abut the oppositeside of the closure 7, and this frame member 10 is preferably provided with an inwardly projecting flange 11 disposed at the outer edge of the frame member 5, said edge and flange serving to clamp the edge of the screen 12, which screen extends across the opening of the frame and prevents the entrance of'insects.

Secured to the frame member 5 by any desired means 13, is an annular frame 14 preferably formed from a single length of wire. Pivoted to this frame '14 on axes transverse to radiithereof, are a plurality of overlapping shutter members 15 which may be swung outwardly or inwardly to any desired extent, and when inwardly swung to the positions of Figs. 3 and l, serve to. substantially excludeair. The edge portions 15 and 15 of each slnitter member 15, respectively overlie and underlie the adja cent edge portions of the adjacent shutter members as will'be clear from Figs. 1 and 3. This insures that uponmovement of any one of said members by hand,the remainder thereof shall simultaneously move n the same manner, said members then sliding upon each other.

Each member 15 preferably consists of a U-shaped wire 16 having its ends bent to form eyes 17 surrounding the frame 1 1, and a flexible covering 18 of leather, fabric or. the like suitably secured to the wire. Bythis construction, the members 15 may be easily and inexpensively manufactured and it will be observed that their eyes 17 serve as their pivotal mountings. i V

Preferably, a knob 19 is secured to the inner end of one of the members 15 for the purposeof swinging this member inwardly or outwardly to effect similar movement of the other members. By preference, this knob is so positioned that it will close the small opening which would otherwise exist at the inner ends of the members 15 when the-latter occupy the positions, of Figs. 3 and 4. Thus, when the members 15 are inwardly swung to the maximum, substantially a tight closure is provided for the windshield opening, and by opening said members more or less, any desired quantity of fresh air may be admitted to the machine,'and it will be observed that this air is screened to prevent the entrance of insects.

The device is exceptionally simple and inexpensive, may therefore be easily and cheaply manufactured, and may be sold at small cost. Yet, when installed, it will be very advantageous and desirable.

As above stated, variations may be made within the scope of the invention as claimed, the present disclosure being illustrative rather than limiting in a number of re spects.

I claim:

1. A, ventilator comprising an annular llll frame, and aplurality of overlapped shutter members pivoted to said frame on axes transverse to radii thereof, whereby said members may be swung inwardly to closed positions or outwardly topartially or fully open positions, said shutter members being connected for movement in unison.

2. A ventilator comprising an annular frame, and a plurality of overlapped shutter members pivoted to said frame on axes transverse to radii thereof, whereby said members may be swung inwardly to closed positions or outwardly to partially or fully open positions, the opposed edge portions of each shutter member respectively overlying and underlying the adjacent edge portions of adjacent shutter members, whereby all of said members must move in unison.

3. A structure as specified in claim 1 each of said shutter members consisting of a U- shaped wire and a flexible covering secured thereto, the ends of the wire being bent to form eyes which surround portions of the frame to pivotally mount the member.

4. A structure as specified.in claim 1;

together with a knob secured to the free end of one of said, shutter members for swinging said members, said knob serving to substantially close the small space which would otherwise exist at the ends of said members when closed.

5A ventilator comprising an annular frame member for passage through an opening in a windshield or other closure, said frame member having a flange at one edge ALBERT ANDREWS.
